SPRING BREEZE - Colour wireless weather station

7.4 Dew point

• Press the HEAT/DEW button, to show the current dew point.
• On the display appears DEW and the dew point temperature.
• The display automatically switches back to the current display of "FEELS LIKE" temperature.
• This interdependency of temperature and relative humidity is expressed by means of the dew-point: If the air is cooled continuously at constant
absolute humidity, then the relative humidity will steadily increase up to a maximum of 100%. If the air is cooled further, then the excess water
vapour is separated out in the form of water droplets.

7.5 Weather forecast symbols

• The weather station has six different weather symbols (sunny, slightly cloudy, cloudy, rainy, stormy and snow).
• The weather forecast covers a range of 12 hours and indicates only a general weather trend. For example, if the current weather is cloudy and the
rain symbol is displayed, it does not mean the product is faulty because it is not raining. It simply means that the air pressure has dropped and
the weather is expected to get worse but not necessarily rain.
• The sun symbol also appears on a starry night.
Note!
• Please note that the forecast symbol will become more defined in the course of operation. The forecast symbol is active right from the start, how-
ever, the reliability of the forecasts increases with the amount of data collected. To begin with, the sensor must adapt initially to the reference
level at the site.

7.6.2 In case of alert
• In case of an alert, the corresponding value will be flashing and an alert tone will sound.
• Stop the alert tone with any button.
8. Base station positioning
• With the foldable leg at the back, the base station can be placed onto any flat surface.
• With the wall mount holes at the back, the base station can be wall mounted at the respective location. Avoid the vicinity of any source of interfer-
ence such as computer screens, TV sets or solid metal objects.
8.1 Combined transmitter installation
• We recommend testing the reception before permanently mounting the transmitter.
• Also make sure that the transmitter is easily accessible for cleaning and maintenance. The outdoor transmitter should be cleaned from time to
time, since dirt and debris will affect the sensor's accuracy.
• Make sure that the wind can blow freely around the anemometer and is not blocked by nearby buildings, trees or any other objects.
• For best results, place the combined transmitter horizontally and at least 3 m above any other objects. The ground below the device creates fric-
tion for the wind and will thus impair the measurements.
• Try to install the combined transmitter so that it will be exposed to the normal wind conditions in your area.
• Attach the combined sensor to a mast with the hole at the bottom of the device.
• Use the supplied support when installing the transmitter on a surface. The support arm may be rotated by 90°. Open the fixing screw and loosen
the support arm. Turn it by 90°, put it back on the bracket and tighten the fixing screw again.
8.2 Additional outdoor transmitters (optional) Cat.-No. 30.3221.02
• When having more than one external transmitter, select a different channel for each one by the CH 1/2/3 switch inside the transmitter's battery
compartment. Insert two new 1,5 V AAA batteries, polarity as illustrated. Start the base station operation or the manual search for the outdoor
transmitter.
• Please note that the combined transmitter is always operated on channel 1.
• Press ▼ button to adjust the respective channel.
• Press and hold the ▼ button on the base station for two seconds. The registered transmitter (channel) will be canceled.
• Press the TX button in the corresponding transmitter's battery compartment. The transmission of the outdoor data takes place immediately and a
successful reception will be confirmed by a beep tone of the base station.
